b. (i) A Group in the modern Periodic Table is completely missing from Newlands' Table. What is the number of this Group? Group number (ii) Suggest a reason why this Group of elements is missing from _(1pt) Newlands' Table. _(1pt) c. Give one difference between iron, Fe, and the other elements in column g of Newlands' Table. d. Give the name of the block of elements in the modern Periodic (1pt) Table which contains Cr, Ti, Mn, and Fe. e. Both Newlands and Mendeleev based their tables on atomic weights. Explain why the modern Periodic Table is based on proton (atomic) numbers. f. The atoms of elements in Group 1 of the modern Periodic Table increase in size going down the group. Explain, in terms of electrons, how this increase in size affects the reactivity of these (1pt) (2pts) elements. _(3pts)
